Releases
Packages
- openssl - Secure Socket Layer (SSL) cryptographic library and tools
Details
David Benjamin discovered that OpenSSL incorrectly handled X.400 address
processing. A remote attacker could possibly use this issue to read
arbitrary memory contents or cause OpenSSL to crash, resulting in a denial
of service. (CVE-2023-0286)
Corey Bonnell discovered that OpenSSL incorrectly handled X.509 certificate
verification. A remote attacker could possibly use this issue to cause
OpenSSL to crash, resulting in a denial of service. This issue only
affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2022-4203)
Hubert Kario discovered that OpenSSL had a timing based side channel in the
OpenSSL RSA Decryption implementation. A remote attacker could possibly use
this issue to recover sensitive information. (CVE-2022-4304)
Dawei Wang discovered that OpenSSL incorrectly handled parsing certain PEM
data. A remote attacker could possibly use this issue to cause OpenSSL to
crash, resulting in a denial of service. (CVE-2022-4450)
Octavio Galland and Marcel Böhme discovered that OpenSSL incorrectly
handled streaming ASN.1 data. A remote attacker could use this issue to
cause OpenSSL to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2023-0215)
Marc Schönefeld discovered that OpenSSL incorrectly handled malformed PKCS7
data. A remote attacker could possibly use this issue to cause OpenSSL to
crash, resulting in a denial of service. This issue only affected Ubuntu
22.04 LTS and Ubuntu 22.10. (CVE-2023-0216)
Kurt Roeckx discovered that OpenSSL incorrectly handled validating certain
DSA public keys. A remote attacker could possibly use this issue to cause
OpenSSL to crash, resulting in a denial of service. This issue only
affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2023-0217)
Hubert Kario and Dmitry Belyavsky discovered that OpenSSL incorrectly
validated certain signatures. A remote attacker could possibly use this
issue to cause OpenSSL to crash, resulting in a denial of service. This
issue only affected Ubuntu 22.04 LTS and Ubuntu 22.10. (CVE-2023-0401)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 22.10
Ubuntu 22.04
Ubuntu 20.04
Ubuntu 18.04
After a standard system update you need to reboot your computer to make all
the necessary changes.
